SMOKE AND GAS COLLECTOR FOR ENGINE-HOUSES.

LOZSASY.

To all whom it may concern:

Be it known that I, HERMANN OLASEN, a subject of the German Emperor, andresident of Schmiedefeld, Germany, have in vented certain new and usefulImprovements in Smoke and Gas Collectors for Engine-Houses, of which thefollowing is a specification.

Hitherto, smoke and gas collectors for engine-houses have become known,in which two semicylindrical flaps, which are movably suspended byhinges from the lead-0H pipe and which inclose the flue-pipe 01 thelocomotive, are by pulling contrivances connected with a throttle fiapwithin said leadoff pipe, so that the latter is closed by saidthrottle-flap, when the two movable flaps are raised from the flue-pipe,while the throttle-flap is again opened when said flaps are again placedupon the flue-pipe. From said known smoke catchers the subject matter ofthe present invention is distinct in that the lower part of the lead-0Epipe is shaped like a hemispherical bonnet, in which a pair of flaps,which correspond to the envelop of the bonnet, are located so as toswing on a common axle in opposite direction, said flaps being adaptedto be turned downward and outward and again to be moved back into thebonnet, thus liberating in the first instance the area of the lead-offpipe in order to embrace the flue-pipe and to make same tight toward theengine-house, while in the second instance they liberate the flue-pipein order to close the lead-off pipe. Hereby, the arrangement of aseparate throttle-flap for closing the leadoif pipe as well as itsconnection with the two other flaps, such as required in the oldarrangements, is avoided, and thus the same result as by the latter isobtained but with simpler means.

The accompanying drawing shows the improved arrangement.

Figure 1 shows the same in a side view, in the position when the engineor locomotive is run beneath the lead-off pipe. Fig.

Patented June 4, 1912. Serial No. 652,653.

2 is a side view of same, in the position before the locomotive is rununderneath. Fig. 3 is a cross section on the line AB of Fig. 1.

a is the lead-off pipe which at its lower part is shaped like ahemispherical bonnet Z).

cl and e are the two closing flaps for the lead-0E pipe, which fit theinner envelop of the bonnet and swing in opposite direction on an axlec. In order to efli'ect this, the axle 0 consists of a core, whichcarries one flap, and of a hollow tube placed above said core, whichcarries the other flap, each flap being adapted to be turned by a leverf and f respectively attached to said core and tube. Upon the two flapsbeing swung downward, which is eifected by a pulling eontrivance gconnected with the levers f, f they embrace the flue-pipe and tightensame toward the enginehouse. Upon the flap being turned back into thebonnet, they liberate the flue-pipe and close the lead-oii' pipe.

I claim:

A smoke and gas collector for enginehouses, comprising in combination aleadott pipe beneath which the flue-pipe of the engine or locomotive isto be placed, a hemispherical bonnet at the lower end of said lead-0Epipe, a pair of flaps corresponding to the envelop of said bonnetmovably arranged within the latter and adapted to be turned in oppositedirection and designed when turned downward and outward to embrace theflue-pipe of the locomotive placed underneath and to liberate the areaof the lead-off pipe, but when again moved back to liberate theflue-pipe and to close the lead-ofi? pipe, for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
